Translation
you were purchased for a price, therefore, glorify THEOS in your body, and in your spirit, which belong to THEOS.
Paraphrase
you belong to God who bought you with the price paid by the blood of Jesus, for that reason you should feel obliged to give THE CREATOR AND OWNER OF ALL THINGS glory by how you use your body, and by what happens in your inner being, both of which actually belong to THE CREATOR AND OWNER OF ALL THINGS.
